FLEXIBLE rirn CONNECTION.

Originai applicatiomfiled Afiri130, 1914, Serial No. 835,490. Divided and this application filed January 16,

Be it known that I, WILLARo of Hornell, in the county of Steuben/and a division.

The object of the invention is to so connect the metal members with the hose member that the-hose will be both compressed and confined. In other'words, in the'prefer able embodiment of my invention, thehose tion is a division. herein relates to the members connecting the is of a longer length than the distance between the metal sections so that when the metal sections aresecured together the hose will be shortened in length, thereby compressing the same. r

The invention consists in the construction and arrangement hereinafter more particu larly described and then definitely claimed.

In the drawings accompanying and forming part hereof: Figure 1, is a side elevation of a pipe connection made in accordance with my invention. Fig. 2 is a vertical centr'al section showing the joint at its normal position. Fig. 3 is a similar section before the parts are screwed home.

Referring now to the details of the drawings by numerals: 1 and 2 designate the fpipe-"connections to be connected by my exible pipe connection. Nothing new is claimed in this application in the parts numbered '1, 4 and 6 for these are specifically claimed in my application, Ser. No. 835,490, filed April .30, 1914, of which this applica- The division claimed pipe .connection 2 with the pipe section 8.

I The'"pi pe section 8 is provided with an en 5O larged socket member 10 which screws onto, one section 12 of a universal joint, this section 12 being loosely connected to a second section 14 of the universal joint which inturn is connected to-the thirdsection 16 and 18 of the joint. The member 18 is screw DODGE, a citizen of the United .States, and a resident means oflinks 52 with of the universal .joint, .this section 18 being screwed into the ring nut 22 connected with. the member 24 projecting "from the pipe.

threaded as indicated at 20 and screws into a ring nut 22. which forms a connection for a member24 screwed onto the pipe connectlon 2. I have thus generally referred tothe parts as illustrated in Fig. 1 and now referto Figs. 2 and 3 for details of construction. As il ustrated in these figures, the enlarged socket end 10 is arranged to receive an enlarged end 44 of a hose section, the other part 46 of which is formed of smaller external diameter and is provided with an annular flange 48. The socket member 10 is arranged to have screwed into it one section 12 of the universal joint, this section being pivotally connected to the second section 14 of the universal joint by means of the pivots 50 shown in Fig. 3. The second member 14 of the universal joint is connected by the third section 18 section 2, all as indicated in Fig. 3. The

construction just described is such that be-.

fore the parts are screwed home, the distance between the end of the first universal joint member 12' and the wall 62 of the member 24 is considerably shorter than the length of the hosev section 44 and 46 so that when the 9 socket member 10 is screwed onto the mem- Patented May a, 1915..

ber 12, the rubber hose section is thereby" shortenedto the extent that the socket mem her is screwed onto the member 12., iii-- 'asmuch as the member 46 of the hose section is the part most easily compressed, it follows that this part is compressed untilthesurplus space is entirely taken up. 'However, a ring 64 is located around the reduced part 46 of thev hose section. This ring is preferably formed of brass, or softer material if pre :ferred, the inner surfaces of which are) slightly rounded as indicated in Fig. 3. This ring is for the purpose of partially filling the space between the shoulder of the member 16. and the section 12 of the universal joint and restrains therubber hose section at this point when it is bent as illustrated in Fig. 2, and prevents the hose from bursting.

When the parts above referred to are screwedhome, the space illustrated in Fig.

3 between the enlarged end of the hose 44 and the ring 64 is entirely closed so that the hose section 46 is considerably compressed. I

' At the same time, it will be'noticed that the 'compressed part of the hose 46 is likewise 1'10 held confined laterally by means of the/section 16 projecting from the member 18 of the universal joint.

It follows from the construction described and illustrated that when either member of the universal joint is moved, the hose section 46 of smaller diameter will accoodate the desired movement. The parts are shown in Fig. '2 as having been moved it Thus it is seen that the upper side. of the hose" section is still further compressed, while the under section isldrawn out so that the space surrounded by the ring greatly increased. However, it is not increased suihciently to relieve the hose sec-- tion from compression but even when moved to the extreme extent shown in Fig. 2, there is no stretching of the parts of the hose section. 0f course there would he a stretching 2o at this point were it not/for the fact that the hose section is so much decreased in length by being shortened as it is compr partially fills the space caused by the opening up of the joint and at the sametime forms a circling hand of metal to coe the gose and thereby prevent y tendency to urst- From the foregoing and accompanying so drawings it will be seen that lhave provided a flexible pipe connection where two or more sections are connected together by a hose member which is confined laterallyiand compressed lengthwise thereof.

, in the form and construction of my'inventionwithout departing from the essential features thereof, the patentable points of which are set forth in the appended claims.

40 What-I claim as my invention is:

' 5 1i Ina pipe connection, two pipe sections connected by a universal'joint, a hose section within said pipe sections and said universal joint and of "greater length,

as before insertion, than the space into which it is fitted, one pipe section having one mem ber. of said universal joint thereto and confining the hose section,a second m mm position. It will be evident that the r. 6%-

It is obvious that changes maybemade member of the universal iointheing pivot- I ally coected to said first member, and a third memher of the universal joint inclosingthe other part of the hose section and connected to the other pipe section and being pivotally connected with the second member of the iversal joint.

'2, In a pipe connection, two pipe sections connected hy a universal. joint, a hose section wit said pipe sections and said universal joint, said hose section having twov parts of diderent diameters and being of so greater leh, hefore insertion, than the space into which it is fitted, one pipe section having one member of said universal joint secured thereto and confining the hose secticn, av second member or said universal joint being pivotally connected to said first imernber, and a third member of said joint the hose section of smaller dieter and chance to the other pipe section and he pivotally connected to the second member of the universal joint.

4. In a'pipe connection, t'wo pipe sections, a hose section. between said pipe sections, a universal joint connecting 'sald pipe sections and'con said hose section at its central part, said hose section being of greater length, before insertion, than the space into which it is fitted.
